Abstract: This paper presents analysis and characterization of
a piezoelectric micro-generator for energy harvesting application.
A low-cost experimental prototype was designed to operate as
piezoelectric micro-generator in the laboratory. An input acceleration
of 9.8m/s2 using a sine signal (peak-to-peak voltage: 1V, offset
voltage: 0V) at frequencies ranging from 10Hz to 160Hz generated
a maximum average power of 432.4μW (linear mass position =
25mm) and an average power of 543.3μW (angular mass position
= 35°). These promising results show that the prototype can be
considered for low consumption load application as an energy
harvesting micro-generator.
